ABSTRACT:
A dispenser contains a product containing bag and a system for generating a dispensing pressure in a chamber created by the space between the product containing bag and the walls of the dispenser. The act of filling the product bag with product to be dispensed establishes an initial dispensing pressure. A pressure regulator in the chamber re-establishes the dispensing pressure after each spray down. The pressure regulator contains a gas and liquid reactant separated from one another and provided in a ratio approximately the same as that of the space within the dispensing container to that of product contained therein.
